HYnRosrArIo MOTOR.

To all whom it may concern:

Be it known that I, JAMES G. MEoHAM, a citizen of the United States, residing at Oakland, in' the county of Alameda and State'of California, have invented new and useful Improvements in Hydrostatic Motors, of which the following is a specification.

This invention relates to hydrostatic motors, and'has for an object to provide a motor of this character with means so that the lifting force of water is concentrated and delivered at one verted into motive power for operating vamachines. A further object of this inventionis to provide a plurality of compartments and means for creating an artificial rise and fall of water adapted to control the movement of buoyant bodies which are provided to operate in their movement adrive shaft, and to provide simple andefiective means for alternately supplying water to and dis charging it from the said compartments.

Other objects and advantages will be apparent as the nature of the invention is better set forth, and it will be understood that changes within the scope of the claims at right angles to Fig.

may be resorted to without departing from the spirit of the invention.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views :Figure l is a sectional view through the hydrostatic motor, parts being shown in elevation. Fig. 2 is a view taken 1. Fig. 3.is an end view. Fig. 4c is a top plan view. Fig. 5 is a sectional view, on line 5-5 of F ig. 6, showing amodification of the ratchet mechanism. Fig. 6 is a section taken at right angles to that shown in Fig. 5.

Referring now' more particularly to the drawings, there is shown a hydrostatic motor 1 comprising a receptacle or tank 2 having a centrally located partition 3 provided with'vertical compartments 4 and 5. The receptacle or ta-nk2 has mounted upon the top thereof brackets 6 and 7 in which is.- revolubly mounted a drive shaft 8, a driven shaft- 9, and a plurality of intermediate shafts l0 and 11. The shaft 8 has keyed thereto a gearwheel one gear of the said train being in mesh Specification of Letters Patent. Application filed October 16, 1908.

point and readily con- 12 adapted to drive a; train of gears 13 upon the shafts 10 and 11,

Patented Aug. 1, 1911. Serial No. 458,070.

said drive shaft is preferably provided with a band pulley. 15 for receiving a belt or the like for transmitting powerfrom the motor to a machine to be operated.

The compartment t has mounted therein a. vertically sliding buoyant body 16, preferably hollow, and is substantially of rectangular form. The compartment 5 has mounted therein a buoyant body 17 of a construction identical to the body 16. The shaft 8 has secured thereto at its ends wheels 18 and 19 each being provided lar series of spur teeth 20. The wheel 18 is constructed in 'such' manner that the teeth thereof normally engage correspondingly shaped teeth 21 upon a vertically disposed rack bar 22 secured at its lower end to the buoyant body 16 seeFigs. land; 2. The teeth of the wheel 19 are engaged with teeth 23 of a rack bar 24 secured at its lower endto the upper end of the buoyant body 17. The rack bars 22 and 24 are slidably mounted through somewhat elongated passages 25 formed .in the top of the receptacle or tank 2, as clearly shown. The rack bar 22 has projecting therefrom a trip element 26, and the bar 24 is provided with a similar trip element 27 for a purpose to be hereinafter described.

Figs. 5 and 6 show a modification of the ratchet mechanism, a hollow spur gear 18 being keyed on shaft 8 and adapted to mesh with a. corresponding rack bar provided interiorly with a clutch disk .or wheel 18 whose teeth engage pins 18 fixed to the body of the gear.-

The tank or receptacle has secured thereto by means ofbrackets 28 vertically disposed with an annuparallel spaced guide ,tubes29 and 30, the

tube 29 being provided for the compartment the -eompartment 5. The tube 29 is provided at its lower end with a coupling mem ber 31 having a pipe connection 32 engaged at one end'iii an opening at the lower end of the compartment 4:, and the said member 31 has depending therefrom'a valve chamber 33 in which is formed a discharge opening 34 for receiving one end of a discharge pipe 35. the chamber 33 is rovided with a valve seat 36 preferably constructed with flaring walls to receiye an inverted cone shaped valve 37 at the lower end of a vertical stem 38 mounted in'the tube 29. The stem 38 is provided Immediately above the opening 34:

4 and the tube 30 being provided for at the upper end thereof with an enlarged head 39 havin a vertically disposed or elongated slot 40 Tormed therein. The tube 30 is providedat its lower end with a coupling member 41 having a pipe connection 42 engaged at one end in an opening at the bottom of the compartment 5. The member 41 has depending therefrom a valve chamber 43 identical in, construction to the chamber 33 and has slidably'mounted therein a valve 44 which is secured at its lower-end to astem 45 adapted to work in the said tube 30. 'The stem 45 is provided at its upper end with an enla-r ed head 46 having an elongated slot 47 ormed therein. The brackets 6 and 7 carry grooved rollers 48 adapted to engage portions of the, rack bars 22 and 24.

An oscillating element 49 is pivotally connected as shown at 50 to a bracket 51 at the top of the tank or receptacle 2 and comprises arms 52, 53 and 54 disposed angularly to each other. The arm 52 has alarly disposed inwardly directed portion 55 at one'end of its outer extremity disposed in the path of movement of-tlie tri 26, and the arm 53 is provided wit a right langularly disposed portion 56disposed in the path of movement of the trip element 27. The arm 52 also has projecting there- 'from a horizontally disposed pin '57 disposed to operate or move in the slot 40' at the upper end of the stem 38. The arm 53 has projecting'therefrom a horizontally disposed pin 58 adapted for operation in the slot 47 at the upper end of the stem 45.

The arm 54 is provided with an angle portion 59 adapted to receive a water discharge nozzle 60 connected'ina suitable manner to a hose or supply pipe 61. It is obvious that the pipe 61 or hose may receive water from any suitable source. A ed upon the to of thetank or receptacle 2 and 18 provide with compartments 63 and 64. The compartment 63 is provided with a depending pipe 65 connected at its lower end to the tank so that water from the said compartment 63 may be conveyed to the compartment 4 ofthc said tank 2. The compartment 64 of the trough .62 is provided with a depending pipe 65 .connected atits lower end with the tank or receptacle 2 so that water from the said compartment 64 may be deposited into the compartment .5 of the receptacle or tank.

The valve chamber .43 is connected by "way of a pipe 66 to a T-coupling 67, the said coupling also receiving the; pipe 35 from.

the chamber33, and as shown, the said coupling has' connected thereto a discharge pipe 68. y

In operation, water is delivered to the hose or pipe tilt and is. discharged from the nozzle 60 into the trou h 62. As shown in -Figs. 3 and 4 the osci lating element 49 is in such position that the nozzle 60 is disposed immediately right angu-' element trough 62 is mountabove the compartment 64 so that water is discharged into the com partment 5 of the tank or receptacle. In the said position of the nozzle the arm 52 ofthe element 49 is raised at its outer end so that the pin 57 is 'at its upward movement, and by reason of the-fact that: the said pin is connected in the manner described to the stem compartment 4 chamber 33 and 67. As soon as has reached the vious that the the portion 56 to pass throughthe valve predetermined level it is obtrip element 27 will enga e of the" arm 53 to accurate y out of the dischargepipe. water in the compartment 5 3s a will be'seen'that the, a valve 37 is displaced or raised' -from .the't. seat 36 to effectively allow'water from the rock the element 49 so that the valve in the chamber 43 is glpened to permit the discharge of water an to simultaneously close the valve in the chamber 33 to prevent the discharge of water.-

he operation of the motor is extremely simple, as the motor is operative parts and is of water to cause the buoyant-- bodies to ascend and descend, as is -obvious,' to trans-.

mit power to the drive shaft 8 throu h the medium of the 'rack bars 22 and 24 an their cotiperating toothed wheels 18 and 1.9 and to finally impart through the said-gear train motion to the driven shaft- Y composed of but few so constructed that'- water from suitable sources may befed alternately into the two compartments of the motor to alternately .efi'ect a rise and fall g Having thus described the'invention whats a 1S claimed as new, is
